世界各国对水泥混凝土路面的设计有着不同的标准与方法,设计过程大都考虑交通荷载、材料特性以及环境条件等因素的影响,而中国由于混凝土路面设计起步较晚,设计方法主要依赖于理论计算,未能充分考虑路面实际使用情况,并且一些水泥混凝土路面确实已经出现不同程度的结构性破坏和功能性缺陷。该文拟对中国以力学分析为基础和美国以经验为依据的水泥混凝土路面设计方法进行对比,为中国水泥混凝土路面设计方法的完善提供一些可供借鉴的经验。
Many countries in the world have different standards and methods for the design of cement concrete pavement. Most of the design process takes into account the influence of traffic load, material properties and environmental conditions. However, due to the late start of concrete pavement design in China, the design method relies mainly on theoretical calculation, Failure to take full account of the actual use of the pavement, and some concrete pavements have indeed experienced varying degrees of structural damage and functional defects. The article intends to compare China ’s cement concrete pavement design method based on mechanics analysis with empirical experience in the United States, and provide some experiences for improving the design method of cement concrete pavement in China.
